LOOK FOR FLUID-DISPENSING APPARATUS.

Application filed February 5, 1925:. Seria1 No.'6,97

"This invention relates to alock for fluid dispensing apparatus and is designed more particularly for use in connection with oil dispensing apparatuses, such'as are'cornmonlyused at automobile filling station's.

Oildispensing apparatuses of this character are frequently left unprotected 'during the absence of the attendant and not infrequently "are left out of doors over night. It is therefore desirable that some means should be provided to prevent the operation of the ump and for preventing accessto the interior of-the tank during the absence of the attendant, and one object of the present invention is to provide such means and, further, to so arrange the same that both the operation of the pump and the closure for the tank will be controlled-by a single look. I I r Dispensing apparatuses of this character are usually located in more or less exposed positions where persons other than the attendant are present or passing and it not infrequently happens that some such person will inadvertently or otherwise impart movement to the pump handle thuscausing 'a loss ofoil. To avoidsu'ch unauthorized operation of the pump it is a further object of the invention toprovide a latch" or temporary lock which is manually controlled and which may be positioned normally to prevent the operation of thepump handle.

These dispensing apparatuses are also sometimesprovidedwith drip pans to catch any drippings from the delivery spout or oil which may be spilled from the measure into which it is discharged from the spout. Where sucha pan is loosely mounted on the apparatus it: is not infrequently lost, either accidentally or due to its removal by boys or other unauthorized persons. A further object of the present 'invention is to provide means, controlled by the lock for the other parts of-the mechanism, which will also prevent the removal of this pan by unauthorized persons.

Other objects of the invention will appear as the apparatus .is described in detail.

In the accompanying drawings Fig. 1 is a side elevation of a dispensing apparatus, showing only the top wall of the tank; Fig.

2 is a section taken on the line 2-2 of Fig.

'1, and partly broken away; Fig. 3 is a detail view of the locking device for the pump showing the same in its'operative position; Fig. 41s a similar view showing the locking device in its inoperative position; and

Fig. 5 is 'a detail View of the lock for the closure for the filling opening to the tank.

In these drawingsI have illustrated one embodiment of my invention and have shown the same as applied to an oil dispensing apparatus of a known character but it will be understood that this particular embodiment has been chosen for the purpose of illustration only and that the looking devices may take various forms and may be applied to dispensing apparatus of va- EioKMEYER, on DAYTON, OHIO, AssIGNon' TO THE rm'riormr. RECORDING rious kinds without departing from the spirit of the invention.

y In that apparatus here illustrated the top wall of the tank is shown at 1 and mounted on this top wall is a base, preferably in the form of a casting 2, on which the dispensing apparatus is mounted. Rising from this base is a hollow standard 8 on the upper end of which is supported a cylinder 4 which, in

the present instance, is of glass and which communicates with the tank through the hollow standard, The upper head of the cylinder 4 is provided with 'a discharge spout 6. Mounted in the cylinder is a piston 7 having a piston rod 8 in the form of a toothed rack bar which extends downwardly into the standard?) and meshes with a pinion 9 mounted on a shaft 10 journaled in the walls of the standard and which is provided on its outer end with an operating handle or crank 11 by means of which. the pinion ma'y be rotated to impart reciprocatory' movement to the piston. The base 2 is provi-ded'with afilling opening which is in line in the to is provide 12. This aterally exwith a corresponding openin wall 1 of the tank and whic with a swinging closure or ca cap is here shown ashaving a tending arm 13 by means of which it is 1 pivoted at 14 on the base 2. Projecting from one edge of the closure is a stop finger 15 arranged to engage a stop lug 16 on the base 2 when the closure is in its closed position and the stop finger and the lug are provided with registering openings to receive a looking device, such as the has p of a padlock 17, to secure the closure or cap in its closed position.

The holding or locking device for the handle 11 of the pump may take various forms but, in the present instance, the handle is so arranged that it will he in its lowermost position, as shown in Fig. 1, when the piston is in its lowermost position, and the holding or locking device, which is shown at 18, is pivotally mounted at 19 on a bracket 20 carried by the base 2. This locking member comprises a finger 21 which is movable into and out of operative relation with the handle 11. In the present construction the handle is provided at its outer end with a recess 22 into which the locking finger 21 may be moved. The locking finger is retained in its operative or its inoperative position by means 01'? a rod which is slidablv supported at one end in the bracket 20 and at its other end in the lug 16, the guide opening in the lug 16 being counterbored to receive the head 24 of the rod. Thus the head of the rod will limit its movement in one direction and the rod will be held against movement in the other direction by the stop finger 15 of the closure 12 when this closure is in its closed position. The end of the rod projects beyond the bracket 20 and into the path of the locking finger 21. When this locking finger is in its locking position, as shown in Fig. 3, the rod will lie beneath the same and will positively prevent its withdrawal. Then the locking finger is in its inoperative position, as shown. in Fig. 4:, the rod will lie above the finger and will prevent its moving into an operative position but will allow it a limited amount of swinging movement, the purpose of which will hereinafter appear. In this manner the lock 17 serves to positively control the movements both of the closure 12 and of the pump-op crating handle 11.

Associated with the locking member 18 and preferably forming an integral. part thereof is a latch 25, which is here shown: in the form ofa finger movable into and out of operative relation to the handle 11, this handle being in the present instance, provided with a, lug 26 to cooperate with the latch 25. The locking member is also provided with. a linger piece 27 by means of which the latch may be moved into and out of its operative position. The locking member as a whole, including the lockin fin er 21, the latch 2-5 and timer piece is so b i a balanced that when the latch 25' is moved into its operative position or into: its inope 'ative position the center of gravity of the locking member as a whole will be shifted from one side of its axis to the other, thus causing the latch to be retained by gravity in either position to which it may be moved.

Mounted on the closure 12, is a housing 28 the upper wall 29 of which. constitutes a support for the measuring cup or other receptacle into which the oil is discharged from the spout 6, this wall having its central portion depressed so that it will slope toward a central opening, thereby causing any oil which may be deposited thereon to. drain through thiscentral: opening into a drippan 30 which is supported within the housing beneath the opening; The housing 28 is provided with an opening 31 through which the drip pan may be inserted and removed and this opening is so arranged with rela tion to the closure 12- that when that closure is in its closed position theopeni'ng' will lie adjacent tothe standard 3 and will be positioned so close thereto that the pan 30 cannot be removed. Consequently the lock 17 which retains the closure in its closed position will also prevent the removal of the drip pa-n 30.
